Comparing the Perfusion and Functional Assessment Capabilities of Electrocardiography- and Photoplethysmography-monitored Phase-resolved Functional Lung and Dynamic Contrast-enhanced Perfusion MR Imaging

Key Points

• The study aims to evaluate and compare the effectiveness of ECG- and PPG-monitored MRI techniques for assessing lung perfusion and function in cancer patients.
• Conducted assessments using electrocardiography and photoplethysmography during MRI scans.
• Evaluated regional perfusion and changes in pulmonary function among thoracic oncologic patients.
• Utilized phase-resolved functional lung MRI and dynamic contrast-enhanced perfusion MRI.
• ECG- and PPG-monitored MRI showed differences in the accuracy of perfusion measurements.
• Assessments revealed distinct profiles in regional lung function changes between the two monitoring methods.
• Findings suggest potential implications for improved diagnostic capabilities in lung cancer.
